2 1 - Technical features Easy to use: the four buttons, the easy-to-read menu structure and the preinstalled application solutions guarantee optimal usability. Simple installation: the 16 A relay means heavy loads can be connected directly without having to use an intermediate relay: compressors up to 2 HP on the basis of the power factor and efficiency of the motor (over 0.65 at 230 V and over 0.85 at 115 V). A vast range of compatible sensor types and screw terminals guarantee highly flexible installation. Unit protection: special software functions, protecting the compressor from voltage fluctuations or high condensation temperature, to guarantee optimal unit performance. Energy efficiency: defrosting on request, day/night mode and intelligent evaporator fan management guarantee maximum energy efficiency. 2 - User interface Button function Press and hold down on startup RESET FACTORY SETTINGS ( FAC is displayed) Press for one second: BACK Press and hold down: PULL-DOWN Press for one second: TEMPERATURE SETPOINT/OK Press and hold down: MENU Display icons Press for one second: UP Press and hold down: ON/OFF Press for one second: DOWN Press and hold down: DEFROSTING Night mode (energy saving) Fan on Defrosting Compressor on Blinks in pull-down mode Alarm activated Units ( C or F) 3 - Quick-start configuration STEP 1: Startup STEP 2: Select quick-start configuration menu Within 30 seconds of startup, press < BACK for 3 seconds. The main switch r12 is automatically set to OFF. STEP 3: Select the preinstalled application o61 The display automatically shows the application selection parameter o61. Press SET to select the preinstalled application. The display shows the default value (for example AP0, blinking). Select the type of application by pressing UP/DOWN and then SET to confirm. The regulator presets the parameter values on the basis of the application selected and hides any irrelevant parameters. Tip: you can easily switch from AP0 to AP6 and therefore select the simplified parameters list by pressing the UP button (circular list). App App 0 App 1 App 2 App 3 App 4 App 5 Description None (no preset application) Medium temperature (4 20 C), without defrost Medium temperature (2 6 C), with timed natural defrost Medium temperature (2 6 C), with natural defrost stop on air temperature Heating Thermostat (20 60 C) None (no preset application) with simplified parameter list STEP 4: Select the sensor type o06 The display automatically shows the sensor selection parameter o06. Press SET to select the type of sensor. The display shows the default value (for example n10, blinking). Select the type of sensor by pressing UP/DOWN (n5=ntc 5 K, n10=ntc 10 K, Ptc=PTC, Pt1=Pt1000) then SET to confirm. NOTE: all the sensors must by the same type. DKRCE.PI.RL0.P2.02 / 520H

3 4 - Menu structure 1) Parameters group SET: press for 3 seconds for state, settings and service 80G Password (if enabled) 3) Value Input states 2) Parameter names Configuration SET Main switch Application SET Application To scroll the parameter names Application 0 Sensor type Application To scroll the parameter groups 5 - Quick configuration with cfg menu Press SET for three seconds to open the parameter groups. Select the cfg menu and press SET to open. The first menu r12 (main switch) is displayed. Set the main switch to OFF (r12=0) to change the preinstalled application. Press UP/DOWN to scroll through the parameters list. Configure the parameter o61 to select a preinstalled application: - Press SET to open the parameter o61. - Press UP/DOWN to select an application (AP0= no application). - Press SET to confirm; o61 is displayed. Continue to set the following parameters (sensor type o06 ) in the cfg menu. DKRCE.PI.RL0.P2.02 / 520H

4 6 - Basic functions Adjusting the setpoint temperature (short press) SET: adjust the setpoint temperature. 80G UP/DOWN: change the temperature setpoint (in setting mode the setpoint flashes). SET: saves the temperature setpoint. Initiate a manual defrost DEFROST: press for 3 seconds to initiate a defsost. DEFROST: press for 3 seconds to stop manual defrost. The DEFROST icon is shown during defrost. Initiate a pull down PULL DOWN: press for 3 seconds to initiate pull down. View an active alarm Pud : is shown for 3 seconds to indicate pull down. The PULL DOWN icon flashes during pull down. PULL DOWN: press for 3 seconds to stop pull down. Temperature and alarm codes alternate flashes until the alarm is resolved. The alarm bell is shown. Unlock keyboard - After 5 minutes of inactivity, the keypad will be locked (if P76 = YES). - When the keypad is locked, if any key is selected, LoC appears on the display. - Press UP and DOWN buttons simultaneously for 3 seconds to unlock the keyboard. unl is displayed for 3 seconds. 7 - Default application settings App Mode Description Temp.
